Step 18: Finishing Touches

Step 19: Plug and Play

Plug it in and rock out. If rocking out is not working, DON'T PANIC! Open the case back up and debug the problem. Here are some tips for debugging...

Building guitar pedals is a time-consuming, often frustrating, and expensive process. If you think you will save time and money by making your own digital delay pedal, I highly advise you to read R.G. Keen's page on the economics of pedal building. However, if like me, you are obsessive, enjoy messing around with electronics and want to make something that looks and sounds uniquely your own, continue reading ahead... just don't say that I didn't warn you!

Follows are detailed instructions on how I made my own digital delay pedal. I must admit that I used a laser cutter as an integral part of the process, but I feel most of the tasks that I am using it for can be performed with many more modest tools. My focus of the Instructable is not so much in the assembly of the circuit, but the assembly of the case, as this is where the real crux of the problem lies. Cramming a lot of things into a little enclosure is not particularly easy. Yet, it's my hope that these instructions will help in some way to simplify the process.

Haven't looked at all 69 previous comments to check if someone caught this - but you have a terrible mistake in your last step. The heading should be "Plug and Pray." Otherwise, nice if incredibly anal job. Much as I love tools, not getting a laser cutter anytime soon.

Nice Job, Pretty Pedal. It looks like you spent a good deal of time working on both the electronics and the object. Some day I should be so focused…

Question for you: I think I would like to use this IC PT2399 for a non-music project, from what you have considered do you think it would be pretty straightforward to make a circuit that is 100% wet (so just passing though the audio with a delay - no feedback, no repeats, ) with 200 or more msec delay? And adjusting the delay a la 0, 50, 100, 200, etc msec? Controlled with a micro controller? Feel free to answer any or all parts.

Hi im delighted to find this project as i needed something for my end of year project for college, just a few questions if you wouldn't mind answering: what type of capacitors are these? e.g panasonic, aluminium? and do i definitely not need an arduino board? also, would you recommend using the full casper schematic or did you make your own for personal reasons or because it was a better layout as such than the original schematic? Thank you!

I really need your help. Your work is awesome and it'll be very much helpful to me. I'm sorry but can you put up some of your conclusions in doing this product since you're the one who've made it. I just really need it for my research. Please be kind to me. Hehe. I'll appreciate your feedback. Thank you. =)

only my comment for this project is only the capacitor uf. has indicated. but the voltage does not. so it can be over voltage the IC and it won"t work properly.. please reply me as soon as possible thanks.....

The SPST switch I was using as a power switch. You can probably use stereo jacks instead of mono such that when you plug in a mono guitar cable have the extra stereo connector complete the circuit by making the ground connection.

oh! I thought "better diagram" meant the one you drew but with better quality. I just wanted to have a better picture of your own diagram, even tho you said that it's almost entirely based on casper one, I still wanted to look into it with its all details. I can't recognize some parts of your version of diagram because of low quality of file, even if I save it on disk and then zoom it, then the quality gets worse and I can't see clearly for example cap marks or any other detail... I'm a beginner amateur electrician so I need to study diagram carefully to get it. please let me have your version of diagram with better quality and sorry for causing so much trouble!
